Research I wrote about earlier may make the whole idea of quantum computing a lot less attractive (they will be able to lie), but researchers in England and Australia have developed ways to make the chips work that's a lot less complicated and less expensive than before.

The core difference between quantum and regular computers is that, rather than using a "standard" bit that can be either a 1 or a 0, quantum computers use a bit of quantum information called a qubit that can exist in several states at the same time, multiplying the amount of information that can be transmitted in a "bit," and with it the potential power of a quantum computer.

Unfortunately, the circuits required to run quantum bits are so complex, the hardware has to dumb down the stream of quantum bits into a stream that can be controlled and used to process data.

Even the circuits that decompose the qubit flow into a logic gate set is so complex in itself that it has made construction of any kind of quantum processor impossible.
